No clue why but activating a lockscreen password on my 620 makes the battery drain much faster than usual. I'm very sure of it because the battery drains about 2% every hour while normally it takes a couple hours to drain that much. I should also mention that I got my screen repaired recently thanks to installing the Amber update which completely screwed up the touch. I don't know if this issue was present before the update or before getting my phone repaired as I never used this feature feature then. Has anybody here experienced this on their phone or have any tips? Thank you in advance!
